Exploratory test of  desulfurization additive HZY-1 in wet desulfurization system of coalfired power plants

Abstract

Abstract:

:Limestonegypsum wet flue gas desulfurization technology is widely taken by coalfired power plants.After desulfurization systems ultralow emission transformation in domestic power plants, most of the desulfurization systems are of excessive sulfur content，low desulfurization efficiency and poor quality limestone， and the slurry making system can not meet the demand. Additive, act as active agent, can be add into the slurry of wet desulfurization absorption tower, which is beneficial to the dissolution of limestone, the absorption of SO2 in the slurry, and the efficiency improvement of desulfurization system.On the other hand,the slurry which is of a low pH range can prevent desulfurization devices from scaling and clogging and maintain the stability of the system。

Key words:

wet desulfurization, sulfur content, desulfurization efficiency, desulfurization additive, slurry
